Coal contains diverse amounts of trace elements in their overall composition (Thomas, 1992).Certain trace elements such as lead, arsenic, cadmium, chromium and mercury if present in high amount could preclude the coal from being used in environmentally sensitive situations (Ward 1984).
Ultimate Analysis of some Nigerian coal - IJEAS
Abstract—Ultimate analysis was carried out to determine the elemental composition of some Nigerian coal samples viz: Garin Maiganga (GMGA3 –top layer and GMGB –base layer), Chikila (CHK), Lamza (LMZ) and Afuzie (AFZ); in order to ascertain their ranks for appropriate utilization.
Coal Composition - an overview | ScienceDirect …
Why is coal composition and quality important to gas analysis? To begin with, the stone composition of coal is analyzed by proximate and ultimate analyses (ASTM, 1993).Proximate analysis determines by using set procedures regarding moisture, volatile matter, fixed carbon, and ash content (Figure 5.21).Proximate analysis is reported by percent on as-received, moisture-free, and moist- and ...

Proximate and Ultimate Analysis | Mining | SGS
SGS uses the results from ultimate analysis tests to determine the elemental composition of the coal including moisture, ash, carbon, hydrogen, nitrogen, sulfur, and oxygen (by difference). We determine each element through stone analysis and express it as a percentage of the total mass of the original coal or coke sample. SGS is a global leader in stone analysis for the coal and coke ...

Nigerian Coal Corporation - Wikipedia
Nigerias coal industry suffered a blow in the 1950s when oil was discovered. Up until this point, the Nigerian Railway Corporation was the largest consumer of coal in the country. However, after the discovery of oil, the Railway Corporation began to replace its coal burning trains with diesel-powered engines. An additional negative impact came when the Electricity Corporation of Nigeria began ...
